Firmware 1.5

Don’t know about anybody else but I’m having trouble changing the vertical scale using the “up” button in “Se” mode. I can move the waveform up and down by holding it as described, but just pressing up doesn’t reduce the volts/division.

Edit: I’ve got hardware v1.1.

Edit 2: The “up” button needs pressed several times in any mode to register it. Is it polled or does it use an interrupt?
